While watching Old Who I was reminded of the things that some period dramas get wrong: bras (LOL, I don't think they had bullet bras back then), make up and even eyebrows.

The Christmas episode will not only give us a new companion (Oswin mentioned her mom, so I'm convinced that Clara will be Oswin's mom), it will also give us a new TARDIS interior. So far I'm unhappy about it, but from experience I know I'll get used to it eventually. Keep calm and don't freak out.
